If the cover is pushed back, there is a risk that it will be pushed back further than is necessary, so that a part of the strand is at least temporarily exposed, which should not be removed. This creates the risk of contamination of this strand part. In particular, this excessive retraction is very disadvantageous in the case of pastes which cure by exposure to light. There is then a risk in the device of the prior art that a front strand part is exposed to multiple light when small amounts are removed in each case, so that this part begins to cure prematurely.

Turning the second cover, the first cover initially remains in its previous position. However, if the stops meet one another, the first cover is rotated and a portion of the paste strand is exposed and possibly lifted out of the ramp.
